Below is an example for the type of questions I used
in my explanation part of the lesson over Mitosis. Also,
the chart below describes each type of question that I
used in my lesson. I used both open and closed
questions. I tried to incorporate questions that would
lead to an effective lesson. My target is success for all of
my students by having effective questioning skills. In
addition, wait time that I used after asking a question
really helped students answer the question thoughtfully.
Way of Classifying Questions
1) Open-ended question- (O)
-Those are the question that involves more thinking and application and are not
direct yes or no question at all.
2) Closed Questions- (C)
-These type questions involve mostly just the factual information and are yes and no
question and very direct questions
3) Rhetorical Question- (R)
-Those question are used to reinforce an idea or to emphasize a point
EXPLANATION
What the Teacher Will Do
and Student
Misconceptions
I will have students divide
in groups of five; I will have
them determine the order of
phases of mitosis by looking
at their sketches. Then I
will have group present their
predictions.
Next, I will talk about what
happens in each phases of
mitosis.
Students in same groups
then will compare the
sketches they drew with the
actual phases of mitosis. I
will have a handout of the
phases of mitosis in order
they appear and have
description of main
characteristic of each
phases. Then I will have
students label what phases
each sketch is in according
to the handout and will have
them fill in main
characteristics of each phase
in their sketches that they
drew observing under the
microscope.
Time: Minutes 40 min
Probing/Eliciting Questions and
Student Responses
What do think the order of phases
should look like in mitosis?
(prophase, metaphase, anaphase,
telophase) (O)
What is most obvious characteristic
to look for when identifying the
phases? (Chromosomes)
{Chromosome position} (C)
In what phase does the
chromosome line in the middle?
(Metaphase) (C)
What is that middle line called?
{equator}(C)
In which phase does DNA
replicate? {Interphase}(C)
Is interphase part of mitosis? (Yes)
{No, only prophase, metaphase,
anaphase, and telophase are part of
mitosis} (C)
How are chromosome pulled apart?
(By these lines){Spindles) (O)
What is each chromosome called
when they chromosome in pair?
(homologous chromosomes)
{Sister chromatid} (C)
How are sister chromatids stuck
together? {By centromere} (O)
Misconceptions:
Does anyone know how the cell
actually splits in two? {The process
What the Students Will Do
In groups of five, students will
determine the order of phases of
mitosis by looking at their
sketches. One person in the
group should record their
prediction. Another person from
the group will present their
prediction.
Students in same group then will
compare the sketches they drew
with the actual phases of mitosis.
They will be given handout of
the phases of mitosis in order
they appear and have description
of main characteristic of each
phases. Then students will label
what phases each sketch is in
according to the handout and
will have them fill in main
characteristics of each phases in
their sketches that they drew
observing under the microscope.
Students do not distinguish
between the terms
chromatin and
chromosomes. Students
believe that spindles work
like rubber bands during
replication. Students are not
aware that endosymbionts
are attached to spindle.
Students are not fully aware
that mitochondria and
chloroplasts self-replicate.
Students believe that
asexual reproduction always
produces identical offspring
cells. Students believe
asexual reproduction results
in weakness and sexual
reproduction always
produces stronger
individual. Students think
haploid cells have half the
traits needed to make an
organism
is called cytokinesis and is starts
during anaphase and ends after
telophase. During this time the
cytoplasm and plasma membrane
of the cells splits} (O)
What would happen if cytokinesis
of the cell did not happen?{the cell
would have twice the number of
normal chromosomes and would
probably die} (O)
Is cytokinesis part of mitosis? (yes)
{no}(C)
What happens in cytokinesis?(two
cells divide) {division of
cytoplasm} (O)
Are daughter cells genetically
identical to parent cells? {yes. No}
(C)
Does anyone know what type of
cells mitosis produces?{somatic,
body} (C)
Why is mitosis is necessary for
your body to undergo?{so you can
heal after injury, to grow} (O)
Knowing that humans have 46
chromosomes, how many
chromosomes are present in
prophase? {92} (O)
Decision Point/Formative Assessment
I will have match up cards activity of phases with the drawings.
The students will work in group of three.
Mitosis match up
card activity.docx
Student Outcomes
What student outcome will
indicate that you should move
on to the elaboration? What will
you do if the outcome is
something else?
If the students have matched all
the cards right then I will move
on. If that is not the case, then I
will tell those students to look at
the Mitosis phase’s handout
again and match up card
according to it. This will help
those students to review the
notes again.
Transition Statement
Mitosis is part of cell cycle. Cell cycle is the series of events that takes place in a cell leading to its
division and duplication (mitosis). Since, we have learned about mitosis and its phases and the order
they appear, what if this isn’t the case? What happens if something goes wrong with cell cycle or
mitosis?
